[0035] See also Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the overall structure of a battery 200 in an embodiment of the present application, Figure 3 for Figure 2 Schematic diagram of the structure without the box cover 12. In some embodiments, the battery 200 includes a chassis 1 and at least two battery modules 4, the chassis 1 includes a plurality of box side panels 11 and a box cover 12, the plurality of box side panels 11 surround the installation cavity 14 and the installation opening 17, the at least two battery modules 4 enter the installation cavity 14 through the installation opening 17, and the box cover 12 is used to close the installation opening 17 to complete the assembly of the battery 200.

[0038] See also Figure 4-Figure 6 , Figure 4 This is a schematic diagram of the structure of two battery modules 4 in one embodiment of the present application. Figure 5 for Figure 4 A top view in the height direction 49, Figure 6 The schematic diagram is a structural diagram of a single battery module 4 in an embodiment of the present application with some components removed. Each battery module 4 includes a bracket 41 and a battery cell group, the bracket 41 includes a side plate 42 and a bottom bracket 43, the side plate 42 is connected to the bottom bracket 43 to form a receiving cavity 44, and the battery cell group is installed in the receiving cavity 44, wherein a protrusion 421 is provided on the side of the side plate 42 of each bracket 41 away from the bottom bracket 43, and a slot 422 is provided on the protrusion 421, and the slot 422 is used for a hanging member 5 to be inserted to carry the battery module 4, and when the two battery modules 4 are installed in place, the battery cell groups of the at least two battery modules 4 are electrically connected.

[0039] Thus, the multiple battery cells 45 in the battery 200 are divided into at least two groups and form at least two groups of battery modules 4, which can reduce the weight of a single battery module 4, so as to reduce the pressure on each bracket 41, avoid the bracket 41 from being damaged due to excessive pressure during transportation, and is also beneficial for operators to operate the single battery module 4, making it easier for operators to carry the single battery module 4, reducing the difficulty of operating the single battery module 4; and, the protrusion 421 is provided on the side plate 42 of the bracket 41 of the battery module 4, and the single battery module 4 is carried through the slot 422 of the protrusion 421, which is also beneficial for operators to operate the single battery module 4, further reducing the difficulty of operating the single battery module 4.

[0040] Each of the battery cell groups is composed of battery cells 45 in the corresponding battery module 4 .

[0041] It is understandable that the bracket 41 and the chassis 1 can be made of, but not limited to, titanium steel or the like.

[0042] See also Figure 7-Figure 9 , Figure 7 for Figure 6 The schematic diagram of the structure without some components. Figure 8 is a schematic diagram of the structure of a bracket 41 in an embodiment of the present application, Fig. 9 for Figure 8Structural diagram with some structures removed. In some embodiments, the side panel 42 includes a side panel body 428 and a first mounting portion 426, the first mounting portion 426 is bent from the side panel body 428 to the outside of the accommodating cavity 44, the bottom bracket 43 includes a bottom plate 432, a side bracket 433 and a second mounting portion 431, the bottom plate 432 is connected to the side bracket 433 and the side panel body 428, the second mounting portion 431 is bent from the side bracket 433 to the outside of the accommodating cavity 44, each of the battery modules 4 is installed in the chassis 1 through the first mounting portion 426 and the second mounting portion 431, that is, each of the battery modules 4 is installed in the mounting cavity 14 through the first mounting portion 426 and the second mounting portion 431.

[0043] Thus, the battery module 4 is installed in the chassis 1 through the first installation portion 426 and the second installation portion 431 , thereby improving the stability of the battery module 4 in the chassis 1 .

[0044] In some embodiments, the number of the battery cells 45 in each of the battery cell groups is less than or equal to 4.

[0045] Thus, the battery 200 of the present application has a total of 8 battery cells 45. In order to reduce the weight of a single battery module 4, the 8 battery cells 45 are divided into at least two battery cell groups, and the number of battery cells 45 in each battery cell group will be less than or equal to 4, which can reduce the weight of a single battery module 4, thereby reducing the pressure on each bracket 41 and avoiding damage to the bracket 41 due to excessive pressure during transportation. It is also beneficial for operators to operate the single battery module 4, making it easier for operators to carry the single battery module 4, thereby reducing the difficulty of operating the single battery module 4.

[0046] It is understandable that the total number of the battery cells 45 can be but not limited to 10, 12, 14, etc., and therefore the number of battery cells 45 in each battery cell group can be but not limited to less than or equal to 5, 6, 7, etc., and is not limited here.

[0047] In some embodiments, Figure 8 As shown, the height of the side plate body 428 in the height direction 49 is higher than the height of the side bracket 433 in the height direction 49 , and the side plate body 428 is perpendicular to the side bracket 433 .

[0048] In some embodiments, the first mounting portion 426 is located at the top of the side panel body 428, that is, the first mounting portion 426 is folded and extended from the top of the side panel body 428 to the outside of the accommodating cavity 44, and the second mounting portion 431 is located at the top of the side support 433, that is, the second mounting portion 431 is folded and extended from the top of the side support 433 to the outside of the accommodating cavity 44.

[0049] In some embodiments, Figure 8 and Fig. 9 As shown, a fixing hole 9 is provided at the bottom end of the side panel body 428, and the bottom plate 432 is bent along the height direction 49 near both ends of the side panel body 428, and the fixing hole 9 is provided, and the screws and the fixing holes 9 are matched to fix the side panel body 428 and the bottom plate 432.

[0050] In some embodiments, each of the brackets 41 includes two side panels 42 arranged opposite to each other, and each of the side panels 42 is provided with a protrusion 421 on a side away from the base 43, and each of the protrusions 421 is provided with two slots 422, and the slots 422 are used for inserting a hanging member 5 to carry the battery module 4.

[0051] Therefore, the two oppositely disposed protrusions 421 can make the process of transporting the battery module 4 more stable and improve the balance and stability of the transport process.

[0052] In some embodiments, the bracket 41 includes two bases 43, which are arranged opposite to each other and connected between the two side panels 42, wherein the bottom plates 432 of the two bases 43 extend toward the inner side of the accommodating cavity 44, but the two bottom plates 432 are not connected as a whole, but when the battery cell 45 is installed in the accommodating cavity 44, the two bottom plates 432 respectively contact the two ends of the bottom of the battery cell 45 to bear the weight of the battery cell 45, so that the battery cell 45 is installed in the accommodating cavity 44.

[0053] In some embodiments, each of the protrusions 421 is bent in a direction away from the battery core 45 .

[0054] In some embodiments, a side of each protrusion 421 facing away from the battery core 45 is perpendicular to the height direction 49 .

[0055] In some embodiments, Figure 8As shown, each of the protrusions 421 is in an I-shape, and each of the protrusions 421 includes a first end 423, a second end 424 and a connecting portion 425, the connecting portion 425 connects the first end 423 and the second end 424, and the two card slots 422 are respectively arranged on the first end 423 and the second end 424.

[0056] Thus, the protrusion 421 is in an I-shape, and the two slots 422 are respectively provided on the first end 423 and the second end 424, so that the hanging component 5 can be more easily inserted into the slot 422 to carry the battery module 4. Carrying a single battery module 4 through the slot 422 of the protrusion 421 is also convenient for the operator to operate the single battery module 4, further reducing the difficulty of operating the single battery module 4.

[0057] It is understandable that the shape of each protrusion 421 may be, but is not limited to, an I-shape, and may also be a T-shape, a Z-shape, etc., which is not limited here.

[0058] In some embodiments, the bracket 41 also includes an isolation sheet 427, which is disposed between every two adjacent battery cells 45 and between the side panel body 428 and the battery cell 45. The isolation sheet 427 isolates every two adjacent battery cells 45 and the side panel body 428 from the battery cell 45, and a portion of the isolation sheet 427 is configured to be hollow to reserve space for expansion and bulging of the battery cell 45 to avoid squeezing of the bulged area.

[0059] In some embodiments, Figure 4 and Figure 5 As shown, each of the batteries 200 further includes a pressure strip 46 , which is connected between the two protrusions 421 , or between the two oppositely disposed side panels 42 , so as to fix the battery cell group in the accommodating cavity 44 .

[0060] Thus, the pressure strip 46 limits the movement of the battery cell group in the accommodating cavity 44 in the height direction 49 to fix the battery cell group in the accommodating cavity 44, further improving the stability of the process of transporting the battery module 4 and reducing the possibility of failure of the battery module 4 during operation.

[0061] In some embodiments, the pressure strip 46 includes a first side 461 and a second side, the first side 461 and the second side are respectively close to the two protrusions 421, the first side 461 and the second side are bent in a direction away from the battery cell 45, and the first side 461 and the second side are parallel to the two protrusions 421 after bending to respectively connect the two protrusions 421.

[0062] Thus, the pressure strip 46 is connected between the two protrusions 421 through the first side 461 and the second side, which reduces the difficulty of operating the single battery module 4 and improves the stability of the process of carrying the battery module 4.

[0063] In some embodiments, Figure 4 and Figure 6 As shown, a column 463 is provided on the side of the pressure strip 46 away from the battery group, and the column 463 is used to install a circuit board 31 . The circuit board 31 is used to detect the working parameters of the battery cells 45 in each of the battery groups and control the working status of the battery cells 45 .

[0064] Thus, the operating parameters of the battery cells 45 in each battery cell group or even the battery 200 are detected through the circuit board 31, and its working state is controlled by the detected operating parameters, thereby realizing the intelligence of the battery 200 and protecting the battery 200 to avoid damage to the battery 200.

[0065] In some embodiments, the fixing holes 9 are provided at corresponding positions of the first side 423, the second side and the connecting portion 425, and the fixing member 48 is inserted into the fixing hole 9 so that the first side 461 and the second side are respectively connected to the two protrusions 421, that is, the connecting portions 425 of the two protrusions 421 are respectively connected.

[0066] It is understandable that the fixing member 48 may be, but is not limited to, a screw, etc., which is not limited here.

[0067] In some embodiments, Figure 4 and Figure 6 As shown, each battery cell 45 in the battery cell group includes a valve 453 , and the pressure strip 46 is provided with a valve hole 462 , and the valve hole 462 is arranged corresponding to the position of the valve 453 of the battery cell 45 in each battery cell group so that the valve 453 is exposed in the valve hole 462 .

[0068] Therefore, the setting of the valve hole 462 allows the valve 453 to be exposed in the valve hole 462, so that when a certain battery cell 45 needs to release the internal pressure, the valve 453 can be opened without hindrance, and the internal pressure can be further released through the valve 453 without hindrance, thereby improving the safety of the battery 200.

[0069] In some embodiments, Figure 4 and Figure 5 As shown, the battery 200 further includes a plurality of first connectors 47 , and the plurality of battery cells 45 in each of the battery modules 4 are connected in series via the plurality of first connectors 47 .

Fig.12 for Fig.11 The schematic diagram of the structure without the circuit board 31 and part of the heat conducting member 35 is shown in FIG. Fig.13 for Fig.12Structural diagram with some components removed. In some embodiments, the battery 200 further includes a second connector 6 and a wire 7, wherein the second connector 6 is mounted on some of the first connectors 47 of the plurality of first connectors 47, and the wire 7 is connected between two of the second connectors 6, so that the at least two battery modules 4 are electrically connected. The first connector 47 and the second connector 6 are connected by welding.

[0076] In some embodiments, one end of the second connector 6 is connected to the wire 7 , and the other end is connected to one end of the terminal 2 located in the mounting cavity 14 , so that the battery cell module 4 is connected to the terminal 2 through the second connector 6 and the wire 7 .

[0077] It can be understood that the first connecting member 47 and the second connecting member 6 can be made of, but not limited to, copper-plated nickel material or the like.

[0078] In some embodiments, the battery 200 further includes an insulating sheet 8 , which is installed on a side of the side plate 42 facing the accommodating cavity 44 and inside the chassis 1 to achieve insulation between the battery cell and the bracket 41 and the chassis 1 .

[0079] In some embodiments, Figure 10-13 As shown, the battery 200 also includes a first heat sink 32, a second heat sink 33, a connecting plate 34 and a heat conductor 35. The first heat sink 32 and the second heat sink 33 are respectively installed on two sides of the circuit board 31, and the heat conductor 35 connects the first heat sink 32 and one side of the circuit board 31, and the heat conductor 35 connects the second heat sink 33 and the other side of the circuit board 31, so that the heat generated by the circuit board 31 during operation is transferred to the first heat sink 32 and the second heat sink 33 through the heat conductor 35, so as to achieve heat dissipation of the circuit board 31.

[0080] As mentioned above, the column 463 passes through the connecting plate 34 to fix the connecting plate 34 to the battery module 4, and the second heat sink 33 is installed on the side of the connecting plate 34 facing away from the battery module 4 to fix the circuit board 31 to the battery module 4.

[0082] Specifically, when the battery 200 includes two battery modules, the number of the terminals 2 is also two, and one of the two terminals 2 is connected to the positive terminal 451 of the first battery cell 45 in one of the battery modules 4 through the first connector 47, the second connector 6 and the wire 7, and the negative terminal 452 of the last battery cell 45 in the battery module 4 is connected to the positive terminal 451 of the first battery cell 45 of the other battery module 4 through the first connector 47, the second connector 6 and the wire 7, and the negative terminal 452 of the last battery cell 45 of the other battery module 4 is connected to the positive terminal of the circuit board 31 through the first connector 47, the second connector 6 and the wire 7, and the negative terminal of the circuit board 31 is connected to the other terminal 2 through the second connector 6 and the wire 7, so as to realize the electrical connection inside the battery 200.
